| Hazard Information | Back Directory | [Description]
Elaidic acid is the major trans fat found in hydrogenated vegetable oils and occurs in small amounts in caprine and bovine milk (very roughly 0.1% of the fatty acids) and some meats. It is the trans isomer of oleic acid. The name of the elaidinization reaction comes from elaidic acid.
Elaidic acid increases CETP activity, which in turn raises VLDL and lowers HDL cholesterol. | [Uses]
Elaidic acid is the 9-trans isomer of oleic acid. It is a monounsaturated trans-fatty acid which can be found in partially hydrogenated cooking oils. In human platelets incubated with arachidonic acid, elaidic acid inhibits HHT and HETE formation while inducing prostaglandin and thromboxane synthesis. | [Definition]
